Application fil ed. January 8, 1908. Serial No. 409,820.

To all whom it may concern:

Be it known that I, HILDUs A. JENsoN, a naturalized citizen of theUnited States of America, residing at Salt Lake City, in the county ofSalt Lake and State of Utah, have invented new and useful Improvementsin Cradle or Rocker Attachments, of which the following is aspecification.

This invention relates to cradles or rocker attachments for babycarriages, and oneof the principal objects of the same is to providesimple and efiicient means for su porting a baby carriage and holding itfirmly in place upon a rocking frame, said rocking frame being supportedupon a wheeled frame so that the entire device may be moved from placeto place.

Another object of the invention is to provide a supporting frame forababy carriage comprising channel iron tracks for the wheels and meansfor locking the wheels in the track, said frame being mounted uponrockers and supported upon a frame provided.

with supporting casters.

These and other objects may be attained by means of the constructionillustrated .in the accompanying drawings, in which,

Figure 1 is a side elevation of a baby carriage supported in the rockerframe made in accordance with my invention. Fig. 2 is a plan view of therocker made on an enlarged scale. Fig. 3 is a longitudinal section ofthe same. Fig. 4 is an end view of the same. Fig. 5 is an underside planview of the caster frame with the rocker frame removed therefrom. Fig. 6is a transverse sectional view of the same. Fig. 7 is a plan view of therocker frame removed from the caster frame. Fig. 8 is a longitudinalsectional view through one of the channel iron tracks and through thecaster frame. Fig. 9 is a detail side view of one of the rockers. Fig.10 is a detail perspective view of one of the keepers for the slidingbolts which hold the carriage wheels in place in the channel irontracks.

Referring to'the drawings for a more specific description of myinvention, the numeral 1 in Fig. 1 designates a baby carriage of theusual construction, and 2 are the wheels u on which the carriage ismounted. A roc er frame for supporting the carriage comprises thechannel iron tracks 3 which are adjustable toward and from each other bymeans of the bolts 4 which extend through the tracks 3 and through slots5 in the cross bar 6 and the rocker bar 7, as shown in Figs. 2 and 4.The rocker comprises the bars 6 and 7 and the intermediate wooden core8. There are two rockers, one at each end of the frame. To hold thecarriage wheels 2 in place in the channel iron tracks 3 I provide asystem of sliding bolts, all operated by a single foot, lever 9 pivotedupon a bracket 10 secured to the bar 6. Connected to the lever 9 is arod 11 connected to a lug 12 formed on or connected to a double elbowlever 13 pivoted at 14 to a central longitudinal bar 15. Connected tothe opposite sides of the elbow lever 13 are oppositely disposed boltrods 16, the outer ends of which are mounted in U-shaped keepers 17adjustably secured to the channel iron tracks 3 bymeans of bolts 18 andslots 19 in the bottom of the channel iron tracks 3. The keepers 17 areeach provided with up. turned ears having slots or openings 20 therein.Similar bolt rods 16 are secured to a double elbow lever 13 mounted uponthe bar 15 and the rod 11 is extended and connected to a lug 12projecting from the elbow lever 13. Keepers 17 a are provided for thebolt rods 16*, said keepers being substantially like the keepers 17previously described, and said keepers being adjustable by similar meansrelatively to the channel tracks 3. Upon the downward movement of thefoot lever 9 the bolt rods 16 and 16 are projected across the channeliron tracks 3 immediately above the fellies of the wheels 2, the resultbeing that the carriage is firmly locked within the tracks 3. To chockthe wheels suitable clamps 21 are provided, said clamps being adjustableupon the tracks 3 to chock the wheels.

The rocker frame is supported upon a caster frame comprising end members22 connected by longitudinal bars 23. The end members 22 each consistsof a sheet metal covering and a wooden core or filling piece 24, theends of the metal cover extending beyond the wooden filling piece andforming bearings 25 for caster wheels 26. The end members 22 have flatupper surfaces 27, as shown more particularly in Figs. 4 and 6. Spiralsprings 28 are disposed at opposite sides of the center of each member22, said springs being secured by one of their ends to brackets 29,while their opposite ends engage nails or pegs 30 secured to the rockers8, as shown in Fig. 3.

From the foregoing, it will be obvious that the tracks 3 may be adjustedtoward and from each other to accommodate baby carriages of narrower andWider gage or tread and that the keepers 17 and 17 a are adjustablelongitudinally of the tracks to insure a smooth operation of the slidingbolts 16 and 16*.

My rocker attachment is of simple construction, can be used with anyform of baby carriage or go cart and has been found a desirable andconvenient device for its pur pose.

Having thus described the invention, what is claimed as new, is

1. A cradle or rocker attachment for baby carriages comprising an upperframe having. channel iron tracks, rockers secured to said frame, meansfor adjusting said tracks toward and from each other, means for holdinga carriage wheel in said tracks, and a frame mounted on caster wheels,said frame being connected to the rocker frame by means of springssecured at opposite sides of the longitudinal center of said frames.

2. In a device of the character described, a rocker frame comprisinglaterally adjustable channel tracks, a system of sliding bolts forsecuring the wheels of the baby carriage in said tracks, a foot leverfor simultaneously operating the system of bolts, a supporting.

frame mounted upon caster wheels, and

springs connecting the two frames disposed upon opposite sides of thelongitudinal center thereof.

3. In a device of the character described, a rocker frame comprisingside tracks, means for adjusting said tracks, means for securing thewheels of a baby carriage in said tracks, rockers comprising an upperstraight bar, a lower curved bar and an intermediate wooden core, asupporting frame mounted on casters and comprising each a metal outsideplate, a wooden lining or filling, and casters mounted in the ends ofsaid metal plates, said frames being connected by spiral springs.

4. In a device of the character described a i frame comprising tracks,rockers upon which said tracks are supported, said rockers eachcomprising an upper flat cross bar, a curved lower bar and anintermediate wooden core.

In testimony whereof I allix my signature in presence of two witnesses.
